PCMflash – 86 Module China Gearbox Activation

PCMflash is a professional ECU/TCU read‑write and tuning tool (often used by tuners and workshops) that supports many vehicle control units. To work with specific ECU/TCU types you must activate modules in the software.

Module 86 “China Gearbox” is one such activation that adds support for TCU/gearbox control units from various Chinese vehicles to the PCMflash software.

This isn’t standalone software — it’s an activation key (license) that you apply to your PCMflash account tied to a USB dongle.
